As illustrated in FIG. 2A-2B, in another exemplary aspect, rounds cavity 120 can be complementarily shaped to rounds 3 to allow the rounds to slidably move within at least a portion of the rounds cavity and to exit through first rounds cavity end 122. Notably, rounds cavity 120 can be structurally configured such that rounds 3 can be introduced into the rounds cavity via at least one of first rounds cavity end 121, second rounds cavity end 122, and a portion therebetween, all of which are deemed equivalents. Further notably, rounds cavity 120 can be provided with any functionally compatible shape, and accordingly, for example and not in limitation, any bottom or side described herein can include any combination of one or more linear and/or curvilinear shapes, including but not limited to, any contiguously positioned side, sides, and/or bottom being similarly, dissimilarly, or identically curvilinear.

Referring now to FIGS. 3A-3C, lower rounds cavity abutment 123, first and second rounds cavity sides 124, 125, and the at least one upper rounds cavity abutment 126 can be positioned to abuttingly limit movement of rounds 3 along a movement plane PM (shown in FIG. 7E) when the rounds exit rounds cavity 120 and into magazine cavity 130, and functional loading of magazine 1 can be effectuated.

As illustrated in FIGS. 3B and 3C, in a particular exemplary embodiment of the present invention, with rounds 3 held within rounds cavity 120, each first round end 4 can be positioned within a first rounds cavity 128 and under at least one upper rounds cavity abutment 126 and/or 127 and each second round end 5 can be positioned within a second rounds cavity 129 and also under at least one upper rounds cavity abutment 126 and/or 127.

As illustrated in FIG. 1A-2B, loader 100 further includes a magazine cavity 130 that can be positioned at first main body end 111. As shown, magazine cavity 130 includes a magazine cavity length 131 that can be less than magazine length 2. Accordingly, in an exemplary aspect, the present invention is not limited to a maximum-length magazine, which can arise when a magazine cavity is configured to encapsulate the entire length of a magazine, which can optionally be provided to the extent desired. Further, in another exemplary aspect, due to the length consideration above, main body length 113 can be reduced, as the main body length would not require inclusion of the full length of a magazine, rendering the overall length of the invention less and therefore more conveniently transportable and/or storable.

As further illustrated, magazine cavity 130 can be complementarily shaped to the shape of magazine 1 so as to facilitate retention of the magazine in a fixed position within the magazine cavity during loading. Accordingly, retention can be effectuated via a friction fit between magazine 1 and a portion of main body 110 that defines magazine cavity 130. Further, alternatively or in combination, retention can be facilitated with at least one of a magazine retention depression 133 and a magazine retention protrusion 134, which can retentionally engage a compatibly configured portion of magazine 1, such as a notch, for example and not in limitation.

Also illustrated, second rounds cavity end 122 can be positioned at second main body end 112, and optionally, shaped to accept rounds 3 into rounds cavity 120. Accordingly, as first rounds cavity end 121 opens into magazine cavity 130, when magazine 1 is positioned within the magazine cavity, rounds 3 can be slidably moved out of rounds cavity 120 along movement plane PM (as illustrated in FIG. 7E), through the first rounds cavity end, and into magazine 1. For example and not in limitation, a user can utilize their finger or any other desired structure that fits within at least a portion of rounds cavity 120 to push a last round 3 b (see FIGS. 5C-5F) towards magazine 1, such that the last round, and any other rounds between the last round and the first rounds cavity end 121, slidably move out of the rounds cavity, through the first rounds cavity end, and into the magazine.

In another exemplary aspect, FIGS. 7A-7D and 8 illustrate additional exemplary embodiments of the present invention that can accommodate the loading of a single feed magazine. As illustratively shown in FIGS. 7A-7D, as rounds 3 positioned within rounds cavity 120 are moved towards magazine 1, each round can successively pivot, such that each second round end 5 is angled towards the magazine. Notably, FIGS. 7A-7D further illustrate optional magazine cavity cover 135, which can be provided as a separate structure or can be integral with loader 100, and can cover at least a portion of magazine cavity 130 (illustrated in FIGS. 7A-7D) and/or rounds cavity 120 (illustrated in FIG. 7C). Further illustrated, optionally, a magazine retention system, such as those integrated with Glock™ firearms can be provided, along with a magazine release 136.

As illustrated in FIGS. 5C-5F, when an exiting round 3 exits rounds cavity 120, the exiting round can abut and force at least one of a follower 1 a and a pre-loaded round 3 a in magazine 1 downwardly into the magazine against a spring force Sp provided by spring S as the exiting round enters the magazine.

FIG. 8 illustrates an exemplary rounds cavity 120 having first and second rounds cavity sides 124, 125 that include downwardly angled portions A-E, which can effectuate such pivoting of rounds 3. In an exemplary aspect, a loader 100 can be provided with any combination of angled portions A-E. Notably, the language “downwardly angled” is intended to represent any angle of first rounds cavity side 124 that is angled towards second rounds cavity side 125, and any angle of the second rounds cavity side that is angled away from the first rounds cavity side. Further notably, any angled portion described herein can be provided with a concave, linear, convex, or irregular shape.

In another exemplary aspect, first rounds cavity side 124 can be provided with a downwardly angled portion A positioned between magazine cavity 130 and second main body end 122, and second rounds cavity side 125 can be provided with another downwardly angled portion E that opens into magazine cavity 130. Accordingly, as rounds 3 are moved towards magazine 1, a pivot point 6 of each round can contact the downwardly angled portion A to pivot the second round end 5 of the round towards the magazine and over the other downwardly angled portion E, before the round subsequently enters the magazine.

As illustrated in FIG. 8, in optional exemplary aspects, downwardly angled portion A can be provided with a convex shape and/or downwardly angled portion E can be provided with a concave shape.
